Beholding Stripe’s excellent documentation and wondering how they’ve built it is a modern technical writing trope. It’s no wonder, then, that when Stripe announced that they open sourced their documentation format and framework, Markdoc, folks would get psyched. I, too, was startled by the sudden release. After some initial doubts, I came to love their approach.
